@Methin: Are you sure they aren't referring to a map? People typically label maps like Excel charts. A-Z across the top columns, 1-100 down the rows to the left. They may be referring to their movements, such as a chess board.

I think that's what he was asking about. Although, I've heard of E6 and E8 but never E7 so maybe that's not it. I never knew the E was supposed to stand for Epic though. Not that it really matters what the E stands for, as long as you know the ruleset E6 refers to.

When you make a full attack, can you make the attacks against different targets, even if your initial target has not died?

If you cannot, is there a feat that allows you to do so?

Expanding on Tedronai's response, even when you take a Full Attack action, you're technically supposed to resolve one attack at a time. This is because you're allowed to stop in the middle of your attack any time you wish, or switch targets (assuming the new target doesn't require you to move in order to hit them). You can even take a 5-foot step between attacks on a Full Attack action, assuming you still qualify for a 5-foot step that turn.
